摘要
We find the gravity dual of a marginal deformation of N = 4 super Yang Mills, and discuss some of its properties. This deformation is intimately connected with an SL(2; R) symmetry of the gravity theory. The SL( 2; R) transformation enables us to find the solutions in a simple way. These field theory deformations, sometimes called b deformations, can be viewed as arising from a star product. Our method works for any theory that has a gravity dual with a U(1) x U(1) global symmetry which is realized geometrically. These include the field theories that live on D3 branes at the conifold or other toric singularities, as well as their cascading versions.
